Sodium Starch Glycolate SDS of Manufacturers

Sodium Starch Glycolate Manufacturers

Sodium starch glycolate is used as a pharmaceutical grade dissolution excipient for tablets and capsules. Sodium starch glycolate absorbs water rapidly, resulting in swelling which leads to rapid disintegration of tablets and granules. It is used as a disintegrant, a suspending agent and as a gelling agent.

Sodium Starch Glycolate BP (Type A)

DEFINITION
Sodium salt of a cross-linked partly O-carboxymethylated potato starch.
Content: 2.8 per cent to 4.2 per cent of Na (A 22.99) (substance washed with ethanol (80 per  cent V/V) and dried).

CHARACTERS
Appearance: White or almost white, fine, free-flowing powder, very hygroscopic.
Solubility: Practically insoluble in methylene chloride. It gives a translucent suspension in water.
Examined under a microscope it is seen to consist of: granules, irregularly shaped, ovoid or pear-shaped, 30-100 µm in size, or rounded, 10-35 µm in size; compound granules consisting of 2-4 components occur occasionally; the granules have an eccentric hilum and clearly visible concentric striations; between crossed nicol prisms, the granules show a distinct black cross intersecting at the hilum; small crystals are visible at the surface of the granules. The granules show considerable swelling in contact with water.

IDENTIFICATION
A. pH (see Tests).
B. Prepare with shaking and without heating a mixture of 4.0 g of the substance to be examined and 20 ml of carbon dioxide-free water. The mixture has the appearance of a gel. Add 100 ml of carbon dioxide-free water and shake. A suspension forms that settles after standing.
C. To an acidified solution, add iodinated potassium iodide solution. The solution becomes blue or violet.
D. Solution S2 (see Tests) gives reaction of sodium.

TESTS
Solution S1: Centrifuge the suspension obtained in identification test B at 2500 g for 10 min.  Collect carefully the supernatant liquid.
Solution S2: Place 2.5 g in a silica or platinum crucible and add 2 ml of a 500 g/l solution of  sulphuric acid. Heat on a water-bath, then cautiously over a naked flame, raising the temperature progressively, then incinerate in a muffle furnace at 600 ± 25 °C.  Continue heating until all black particles have disappeared. Allow to cool, add a few drops of dilute sulphuric acid, heat and incinerate as above. Allow to cool, add a few drops of ammonium carbonate solution, evaporate to dryness and incinerate cautiously. Allow to cool and dissolve the residue in 50 ml of water.
Appearance of solution S1: Solution S1 is clear and colourless.
pH: 5.5 to 7.5. Disperse 1.0 g in 30 ml of water.
